2. IMMUNOASSAYS: Immunoassays use specific antibodies or antigens to detect the presence of a target analyte. Various formats, such as enzyme-linked immunosorbent assays (ELISA) or lateral flow assays, are utilized in qualitative immunoassays. 3. SPOT TESTS: Spot tests involve the application of a specific reagent directly to the sample. The appearance of a characteristic color, precipitation, or other observable changes indicates the presence of the analyte. 4. ODOR OR TASTE TESTS: Some qualitative tests rely on sensory evaluation, such as identifying specific odors or tastes associated with certain substances.
